I got some weird “Duplicate Entry” Exceptions on creating content after doing a database migration to Drupal. It comes after registration if you added few users to db directly, or will come on creating new content if you added nodes directly to db.

Actually there is no AUTO_INCREMENT set for db tables in drupal, instead there is a ’sequences’ table. So make sure you make appropiate changes to numerical values after migration.

BTW, if you came here looking for how to migrate to Drupal from other CMS (wordpress, geeklog etc.. ) read these articles on drupal handbook.
